Description

[0001] The invention relates to a mobile, ultra-high-speed data transmission system, i.e., at a rate exceeding 500 megabits per second. In particular, it relates to the transmission of ultra-high-speed data from an outdoor location to a terminal located indoors.

[0002] Transmitting data to an indoor space at ultra-high speed is made difficult by the challenge of getting signals through building walls.

[0003] The technology for transmitting signals from outdoor radio stations to indoor spaces is already known. One such solution is an indoor 4G box or 4G dongle. However, it doesn't achieve ultra-high-speed performance due to insufficient coverage of high frequencies inside buildings for the downlink, and the lack of directivity of its antenna system for the uplink. Another solution is an outdoor "CPE Outdoor" system. However, due to its size and required equipment, this solution is very intrusive, difficult to install, and expensive. In particular, it requires complex installation involving drilling or the use of cumbersome mounting systems.

[0004] US2016 / 197434 discloses a data transmission system comprising an outdoor camera and an indoor WiFi unit, connected by wired data transmission means extending between a sash and a frame of a wall, and by wired electrical connection means extending between the sash and the frame.

[0005] US2019 / 215065 discloses a data transmission system between two data transmission units, located on either side of a wall, and communicating wirelessly.

[0006] According to document FR1874196, filed on behalf of the applicant, a high-speed transmission system through a window is known, comprising two transmission units fixed to each other on either side of the window. Data transmission between the outdoor and indoor units is achieved via Wi-Fi. Furthermore, the indoor unit provides power to the outdoor unit via wireless charging. This system overcomes some of the drawbacks of previous solutions because it allows for high-speed transmission, i.e., 350 megabits per second downstream, while being significantly simpler and less expensive to install than the "Outdoor CPE" type solution.

[0007] However, this system has several drawbacks in practice.

[0008] On the one hand, it does not allow for ultra-high-speed transmission, meaning the transmission of data from the outside to an inside terminal at a rate exceeding 500 megabits per second. This is because using Wi-Fi between the two units requires allocating half of the available bandwidth, thus halving the remaining data transmission rate between the indoor unit and the intended indoor terminal. To compensate for this loss, using 802.11ac triple-radio MIMO 3x3 or 802.11ax MIMO 4x4 Wi-Fi routers is prohibitively expensive. Furthermore, it is necessary to guarantee wireless power transmission between the two units in the worst-case scenario, such as a thick window. However, in this case, the size of the antenna systems becomes excessive, and the power consumption too high.Furthermore, this wireless transmission generates a thermal impact that is difficult and costly to control and requires restrictive dimensional adjustments.

[0009] The invention aims in particular to provide a mobile data transmission system with a speed exceeding 500 megabits, which is inexpensive and very easy to install.

[0010] For this purpose the invention relates to a data transmission system through a wall comprising an opening hinged on a fixed part as defined in claim 1.

[0011] Thus, the system leverages the hinge of the sash on the frame to extend the electrical and data transmission connections through the wall, eliminating the need for drilling or complex fixing methods. It is particularly easy to install. The wired data transmission allows for speeds exceeding 500 megabits per second, preferably greater than or equal to 1 gigabit per second, avoiding the bandwidth loss that would result from using Wi-Fi. Compared to a wireless power transmission system, the wired electrical connection reduces power consumption and decreases the size and heat output of the system components. The invention therefore provides a highly portable system—that is, one that is simple to install and easy to handle—enabling ultra-high-speed data transmission without the need for additional expensive components.

[0012] Advantageously, the wired means of data transmission and / or electrical connection have a generally flat shape so as to be able to extend between the complementary adjoining surfaces of the opening and the fixed frame when the opening is in the closed position on the fixed frame.

[0013] Thus, the means of transmission and / or electrical connection do not interfere with the closing of the sash onto the frame. They are therefore particularly discreet and unobtrusive.

[0014] Advantageously, the means of wired data transmission and the means of wired electrical connection include a common Ethernet cable capable of both transmitting data at a rate greater than or equal to 500 megabits and transmitting current.

[0015] Thus, Power over Ethernet (PoE) is used to transmit both ultra-high-speed data and electrical power from one unit to another via a single cable. This technology further reduces the system's size constraints by eliminating the need to handle and position multiple cables, and simplifies installation.

[0016] Preferably, the throughput is greater than or equal to 750 megabits per second, preferably greater than or equal to 1 gigabit per second.

[0017] Thus, the system allows transmission from outside to a terminal located inside, with a particularly high throughput, while being particularly simple to handle and inexpensive considering the elements that compose it.

[0018] The system includes magnets cooperating by attraction so as to fix the units to the wall by clamping the wall between these units.

[0019] This magnetic system eliminates the need for drilling and screws, significantly increasing installation ease. It also allows for the removal of units from the wall without damage or special disassembly, which is essential if the user frequently moves the system between different residences or stores it indoors, for example, during an extended absence. Magnetic attachment is also advantageous compared to adhesive mounting. The inventor determined that attaching and removing transmission units from walls, particularly using so-called "nanotape," presented several technical problems. First, these tapes leave marks on windows. Furthermore, repeated repositioning of the units degrades the tapes, eventually diminishing their adhesion.This phenomenon is aggravated outdoors due to temperature variations, and to counteract it is necessary to regularly clean the walls, without any guarantee of a return to proper adhesion.

[0020] In other words, using nanotape strips risks causing units to fall, their maintenance is tedious, and they don't guarantee that the units will stay in place. Therefore, using magnets, which are durable and require no maintenance to maintain their adhesion, is preferable to adhesive strips. Furthermore, moving units secured with magnets leaves no marks on the walls.

[0021] Advantageously, one of the magnets being a main magnet, at least one of the units has a magnet housing, the housing including a shoulder for positioning the main magnet, the shoulder separating a first part of the housing intended to house the main magnet from a second part of the housing which can be used to house, if necessary, one or more additional magnets.

[0022] Thus, the magnet(s) that secure the unit to the wall are housed within the housing. The housing is designed to accommodate one or more magnets, allowing the desired level of magnetization to be adjusted, particularly depending on the thickness or type of the wall against which the units are mounted. If a standard level of magnetization is required, for example, because the wall is a typical double-glazed window, only the main magnet needs to be housed in the housing. This magnet will then rest against the positioning shoulder, ensuring it remains in the first part of the housing. Conversely, if a higher level of magnetization is desired, for example, because the wall is a particularly thick triple-glazed window, then it may be necessary to add one or more additional magnets to the housing in addition to the main magnet.In this case, the additional housing(s) are sized so as not to abut against the shoulder and therefore to fit into the second part of the housing, while the main magnet remains positioned in the first part, against the shoulder. Because the housing is designed to allow these different configurations, the same housing, and therefore the same system, can be mounted on walls of varying thicknesses or even different types. It is therefore unnecessary to design housings specific to a particular magnetization level; additional magnets can simply be added to the housing as needed. This can even be done during unit installation while testing the different magnets. Naturally, it is advantageous for all unit housings to be constructed in this way, for example, with four such housings per unit, one at each corner.

[0023] These housings therefore solve the technical problem of adapting the magnetization to different surfaces. The main magnet can thus be adapted to most windows, with additional magnets added for windows thicker than normal.

[0024] Preferably, the main magnet, the additional magnet(s) and the housing have a general cylindrical shape of revolution, the first part having a first diameter, the second part having a second diameter smaller than the first diameter, the second part being coaxial with the first part.

[0025] Thus, for mounting to a standard wall, only the main magnet, designed for normal magnetization, is inserted into the housing. Within the housing, it sits in the first section, butting against the shoulder formed by the diameter reduction at the entrance to the second section. It may extend throughout this first section so that it is flush with the opening of the housing and therefore as close as possible to the wall. If additional magnets are needed, they are inserted into the housing before the main magnet, taking their place in the second section while being magnetically attached to the main magnet, which remains in the first section.

[0026] This housing arrangement, consisting of two cylindrical sections of different diameters, allows, in other words, for the insertion of either the main magnet alone, since it will be held in position by the shoulder and leave the second section of the housing empty, or an assembly of magnets inserted as a single unit, comprising the main magnet and one or more additional magnets magnetically attached to it. Changing the magnetization level is therefore particularly easy. Specifically, with cylindrical neodymium magnets of the same type, the magnetization level depends on the height of each magnet inserted into the housing.Therefore, many combinations of magnets can be inserted into the housing, ranging from a single main magnet held in position by the shoulder, to three, four or more magnets including the main magnet and additional magnets taking place in the second part of the housing and held in position by their magnetization to the main magnet.

[0027] Alternatively, a shorter main magnet can be used compared to the height of the first part of the housing. In this case, to ensure the magnet is flush with the housing opening and remains as close as possible to the wall, a magnet support is added to the first part of the housing. This support is not magnetized; it could be, for example, a hollow plastic cylinder. This alternative aims to reduce the magnetization level compared to that of the standard main magnet.

[0028] Thus, the housing allows the desired magnetization to be adjusted as desired between the units located on either side of the wall, so as to achieve the desired adhesion force regardless of the wall separating the units.

[0029] Advantageously, the first unit includes a first wireless data transmission interface to and from a first remote device, and the second unit includes a second wireless data transmission interface to and from a second remote device.

[0030] Thus, one unit, specifically the one located outdoors, can communicate with a mobile network, for example via a cell tower, a ground-based radio station, or a satellite, while the other unit, located inside a space on the other side of the wall, can communicate with a user's terminal. The system then provides downlink transmission from the outside to the terminal at a speed exceeding 500 megabits per second, and uplink transmission at a speed of 100 megabits per second or higher. This speed is made possible, in particular, by having one unit outdoors and another indoors.

[0031] Preferably, the first interface includes: an antenna equipment capable of receiving signals on mobile network usage frequencies below 6 GHz with a gain greater than or equal to 6 dBi, a radio equipment supporting a downlink data rate greater than or equal to 500 megabits per second, a router supporting a downlink data rate greater than or equal to 500 megabits per second and having a "PoE In" type Ethernet port supporting a downlink rate greater than or equal to 1 gigabits per second, preferably greater than or equal to 10 gigabits per second.

[0032] Thus, each of the elements comprising the first interface is capable of extracting ultra-high-speed data, particularly from external sources via mobile networks such as 4G or 5G, and transmitting this ultra-high-speed data to the second unit located on the other side of the wall. Throughout the application, the term "mobile network usage frequencies" refers, for example, to the following bands: A 700 MHz, bands 12, 13, 14, 17, 28, 29, 44, 65, 68, 85, n12, n14, n28, n29, n83 A 800 MHz, bands 20, n20, n82, n99, bands 20, n20, n82, n9, 800 MHz, bands 5, 18, 19, 26, n5, n18, n89, A 1 500 MHz, bands 50, 51, 75, 76, n50, n51, n74, n75, n76, n91, n92, n93, n94, A 160 MHz, 204 MHz band bands 4, 70, n66, n86, A 1800 MHz, bands 3, n3, A 1900 MHz, bands 2, 25, 37, n2, n25, n39, A 2000 MHz, bands 34, n70, A 210 MHz, 11, 65 MHz n34, n65, n84, n95, A 2300 MHz, bands 30, 40, n30, n40, A 2400 MHz, band 53, A 2500 MHz, bands 41, n41, n90, A 2600 MHz, bands 73, 38, 38, n97 A 3300 MHz, bands 52, n77, n78, A 3400 MHz, bands 42, n77, n78, A 3500 MHz, bands 42, 48, 49, n48, n77, n78, A 3600 MHz, bands 43, 48, 84, n78 n77, n78, A 3700 MHz, bands 43, n77, n78, From 3800 MHz to 4200 MHz, band n77, From 4400 MHz to 5000 MHz, band n79.

[0033] Advantageously, the second interface includes: a "dual band" type antenna equipment capable of receiving a data rate in Wi-Fi greater than 500 megabits per second, a radio equipment supporting a downlink data rate greater than or equal to 500 megabits per second, a router supporting a downlink data rate greater than or equal to 500 megabits per second and having an Ethernet port supporting a downlink rate greater than or equal to 1 gigabit per second, preferably greater than 10 gigabits per second.

[0034] Thus, each of the elements composing the second interface is capable of extracting ultra-high speed data from the first unit, and transmitting this data at ultra-high speed to a user terminal, such as a computer, located in the interior space.

[0035] This arrangement therefore allows ultra-high-speed transmission, in particular a speed of at least 500 megabits per second at least in downlink, from outside to inside a room or residence.

[0036] Preferably, at least one of the units includes a dynamic IP address distribution server.

[0037] Thus, it is possible to easily connect a device with a LAN type communication interface (from the English "Local Area Network" which means "local network") without requiring complex configuration, and then to easily benefit from the data transmission system operating as a gateway between the remote network (for example a 4G or 5G type telecommunications network) and a home type local network, internal to a premises or a home (for example a WiFi wireless local network).

[0038] Advantageously, at least one of the units has a total volume less than or equal to 1200 cubic centimeters.

[0039] Thus, the two units can have dimensions not exceeding 15*15*5 centimeters, in order to optimize their discretion and facilitate their installation. Each unit can therefore be easily removed and moved, making the system particularly portable.

[0040] Preferably, the opening forms a living window.

[0041] Indeed, the invention is particularly well-suited to windows. Generally, within a window, a flexible insulating seal separates the sash from the frame at the sash's axis of rotation, so the wired means of the invention can be positioned there. In the closed position, these means compress the flexible seal without hindering the window's opening or closing, remaining discreet while maintaining the window's insulation. Furthermore, windows are generally thinner than walls, which allows, for example, the use of neodymium magnets to attach the units to either side of the window.

[0042] Furthermore, the maximum thickness of most windows can be predicted so that the magnets can be sized to function even in this case, and therefore in all cases. Specifically, magnet housings can be designed with a first section sized to hold a main magnet in position, which will be suitable for most window surfaces. A second section of the housing is sized to accommodate one or more additional magnets in cases where the window thickness is greater than normal.

[0043] Finally, generally, windows separate an interior room from an exterior space free of nearby obstacles, which allows good data transmission between a radio station and a unit of the invention located on the exterior surface of the window.

[0044] The invention also provides a method for installing a data transmission system as described above, in which, the wall having a flexible seal between the opening and the closing, the data transmission means and the electrical connection means are extended through the wall between the opening and the seal, so that, once extended, the data transmission means and the electrical connection means do not interfere with either the opening or the closing of the opening.

[0045] Indeed, some walls with a hinged opening on a fixed frame, such as most windows, have a flexible insulating seal between the window frame and the window's axis of rotation, along this axis. The system installation therefore involves utilizing this space, compressing the flexible seal to accommodate the transmission and connection means between the two units, preferably in the form of a single, thin, flat Ethernet cable.

[0046] Advantageously, the wall separating an exterior space from an interior space, The first unit is fixed to a surface of the wall facing outwards, the second unit is fixed to a surface of the wall facing outwards, and the second unit is connected to a power supply located in the interior space.

[0047] Thus, the unit located outside is powered by the power supply from the unit located inside, via the electrical connection means between the two units. Brève description des figures

Description détaillée

[0049] The following description will focus on a particular embodiment of the invention: the transmission of data through a residential window. However, the invention is, of course, generalizable to any type of wall comprising a hinged opening on a fixed frame.

[0050] We have represented on the figure 1 a diagram of an embodiment of the invention, some elements of which are also illustrated in the figure 2 This data transmission system 1 comprises two data transmission units 11 and 12. These units 11 and 12 have respective housings located on either side of a window 13. This window 13 is illustrated in the figure 2 The unit has a transparent wall and can be opened by rotation around an X-axis, at which point it is mounted to a wall 14. It therefore comprises an opening 13 and a fixed part, the wall 14. This wall 14 separates the interior of a commercial space from the exterior. The data transmission unit 11 is thus positioned on the exterior side of the window 13 and is wirelessly connected to a radio station 15 belonging to a mobile network. The unit 12 is located on the opposite wall of the window, therefore within the interior space of the commercial space. It is wirelessly connected to a terminal 16, such as a computer. This system 11 allows data to be transmitted from the station 15, located outside, to the computer 16 located inside, at a download speed of 1 gigabit per second or higher. The upload speed is 100 megabits per second or higher.

[0051] We will first describe the assembly of units 11 to 12 to each other on either side of window 13. Then we will describe each component of each unit, explaining how ultra-high speed is achieved from station 15 to computer 16.

[0052] Each unit comprises an antenna system, a radio system, and a router. Hereafter, "antenna system" refers to one or more antennas, possibly with associated configuration or connection components. "Radio system" refers to a modem, or similarly functional equipment, possibly with associated configuration or connection components. All three components are housed in a single enclosure (each unit 11 or 12) measuring 15 centimeters high, 15 centimeters wide, and 5 centimeters deep. Therefore, each unit has a volume of 1125 cm³. The fact that each unit does not exceed 1200 cm³ makes this system particularly easy to handle, as each unit is simple to install. The 5-centimeter depth also allows units 11 and 12 to be mounted on a window without interfering with any shutters.Indeed, on average, the distance between a shutter and a window frame is about 5 cm, and in the worst cases, 3 cm. Let's therefore maintain this maximum of 3 cm between the frame and the shutter. The distance between the frame and the surface of a window, that is, the thickness of the exterior frame, is generally equal to the thickness of the window divided by two, to which we should add approximately 2 cm. Thus, in the worst-case scenario, the distance between the window and its shutter is 2 + 3 = 5 cm. This is why it is advantageous for the depth of the units, at least that of the exterior unit 11, to be 5 centimeters.

[0053] Thanks to its small size, system 1 is therefore particularly portable, especially since it does not require a complex fixing system or difficult installation operation.

[0054] Indeed, to fix units 11 and 12 on either side of window 13, neodymium magnets 17 are used, each unit having four magnets 17, placed at the four corners of unit 12 on the figure 2 and of course, in the same way on unit 11 (not shown). They are placed specifically inside the unit, separated from the window by a cover (not shown) that is either clipped or screwed onto the unit. By placing units 11 and 12 opposite each other on either side of the wall 13, the neodymium magnets 17, attracted to each other, hold units 11 and 12 against their respective walls of the window 13. Thus, the magnets 17 allow these units 11 and 12 to be easily fixed around the window 13, without the need to drill holes in a wall, use glue, screws, or install a complicated fastening system. Their removal is also facilitated.

[0055] Generally, the magnets 17 are designed and sized to secure units 11 and 12 to each other through a window with a wall thickness of approximately 30 millimeters. Single-pane windows are typically 4 to 6 millimeters thick, but the vast majority of double-glazed windows are either 24 millimeters thick (two 4-millimeter panes of glass separated by a 16-millimeter air gap) or 28 millimeters thick (two 4-millimeter panes of glass separated by a 20-millimeter air gap). Therefore, the magnets 17 are designed to securely hold units 11 and 12 together, even in the worst-case scenario, i.e., when the window thickness is around 30 millimeters.

[0056] In particular, a first method of attachment can be provided using cylindrical neodymium magnets of revolution, 20 millimeters in diameter and 4 centimeters in height. Furthermore, to reinforce the adhesion of units 11 and 12 to the window 13, non-slip plastic pads (not shown) can be placed directly above each magnet 17 on the units, that is, at the four corners of the unit's cover, between the cover and the window. Of course, the magnets could be of a different type. In general, the attachment methods could vary.

[0057] We will now describe a second method of magnetic attachment with reference to figures 4 à 9 in which the level of magnetic attraction can be adjusted so that the adhesive force of the units remains suitable for any wall or wall thickness. In particular, this force must provide a good compromise between the reliability of the attachment and the ease of handling the equipment for repositioning. In this mode, recesses 31 are formed at the four corners of each unit 11 and 12. The figure 4 The diagram schematically illustrates the four housings 31 of any one of these units without a cover, so that the entrance to each housing and its extent within the unit are shown in dotted lines. The housings 31 are cylindrical and each comprises two parts. The first part 32 has a diameter of 20 mm and a depth or height of 20 mm. This part 32 is flush with the opening of the housing 31; therefore, this part of the housing is intended to be closest to the window 13 or any wall when the unit is fixed. The second part 33 is located coaxially with the extension of part 32. Its height is also 20 millimeters. However, its diameter is smaller, at 19 mm. This difference in diameter between parts 32 and 33 results in a shoulder 34 at the boundary between the two parts of the housing 31.This dwelling 31 is shown empty in the diagram. figures 4 And 5 However, to fix the units together on either side of window 13, each of the four slots in these two units houses at least one magnet, with the four magnets facing each other in pairs. The shape of the slots 31 also allows for the insertion of additional magnets if necessary, depending on the desired level of magnetization. We will describe some of these variations below.

[0058] There figure 6 This illustrates the case of a magnet 35 housed in the first part 32 of the housing 31. The magnet 35 is sized so that it butts against the shoulder 34 on one side and is flush with the opening of the housing 33 on the other; it therefore measures 20 millimeters in height and 20 millimeters in diameter. As in the following variants and as indicated above, the magnet flush with the opening of the housing is not in direct contact with the wall, a cover being attached to the unit by clipping or screwing. On the other side of the magnet, the part 33 of the housing remains empty in this variant. Placing one magnet 35 in each housing 31 at the four corners of each unit is suitable for fixing these units on either side of a 24-millimeter-thick window. Indeed, the mutual attraction exerted by these eight magnets on a 24 millimeter window generates an adhesive force of 6 Newtons.

[0059] In another variant illustrated at the figure 7 Each housing 31 is equipped with a magnet 36 in addition to the magnet 35. This magnet 36 measures 10 millimeters in height and 19 millimeters in diameter so that it can be inserted into the second part 33 of the housing 31. Thus, during the assembly of the unit, with the cover removed, the assembly formed by the magnet 35 and the magnet 36, which will have been previously magnetized to each other coaxially, is inserted into the housing 31. The magnet 36 will take its place in the second part 33 while leaving an empty space and remaining attached by magnetism to the magnet 35, which remains extended in the part 32 between the shoulder 34 on one side and the cover on the other when the latter is then fixed on the unit. The mutual attraction exerted by these eight assemblies on either side of a 24-millimeter window generates a friction force of 8 Newtons. Around a 27-millimeter window, the friction force is 6 Newtons.

[0060] There figure 8 This illustrates an assembly of three magnets in housing 31, comprising one magnet 35 in part 32 and two magnets 36 in part 33. Placed end to end, these magnets fill the space in part 33 so that the entire housing 31 is filled with magnets. The adhesive force generated by four such assemblies on either side of a 24-millimeter window is 9 Newtons, and 6 Newtons for a 29-millimeter window.

[0061] Thus, housing 31 allows for the integration of several separate magnet assemblies, enabling the selection of the desired magnetization level, depending in particular on the window thickness or the type of wall. A holding force of 6 Newtons is advantageous as it provides a good compromise between secure positioning on the wall and ease of manipulation for repositioning the units if necessary.

[0062] In contrast to the variants described previously, it is also possible to reduce the adhesive force compared to that of a single magnet 35 per housing 31. The figure 9 This illustrates a variant where a magnet 37, 20 millimeters in diameter but only 10 millimeters high, is inserted into the housing 31. To ensure it is flush with the cover and therefore with the window, a support 38, in the form of a hollow plastic cylinder 10 millimeters high and 20 millimeters in diameter, is inserted upstream into the housing. Together, the support 38 and the magnet 37 complete part 32 of the housing 31, leaving part 33 empty. In this variant, the adhesive force generated by mutual attraction, for eight such assemblies (four per unit on either side of the wall), is 30 Newtons for a single 6-millimeter pane of glass. By reducing the height of the magnet to 3 millimeters and therefore increasing that of the support to 17 millimeters, we obtain a force of 7 Newtons which is well suited to the invention.

[0063] The housing of the invention is not limited by the variants described above. In particular, it is possible to provide a housing of different dimensions, even with more than two parts and therefore at least two shoulders within it. Similarly, the magnets to be inserted into it can be segmented in an unlimited number of ways, so as to adjust the desired adhesive force very precisely.

[0064] The other elements of the units described below are naturally compatible with all magnetization variants, as well as generally with any type of unit mounting.

[0065] Units 11 and 12 include means for transmitting data to each other, and means for electrical connection. In the embodiment illustrated in figures 1 et 2 These methods are common. They involve a short, flat Ethernet cable (in this case, 25 centimeters long), Category 7, and 2 millimeters thick. It could be another type of cable, for example, a shielded Category 7e cable, or any type of cable 2 millimeters or less thick that supports PoE (Power over Ethernet), as we will discuss later. Generally, it is advantageous for the cable thickness to be no more than 3 millimeters so that it can be inserted into most of the gaps between windows and their frames, as we will also describe below. The proximity of units 11 and 12, due to the window's relatively thin profile compared to that of a wall, allows for the use of a particularly short cable, which could, for example, be as short as 50 centimeters.

[0066] Utilizing 802.3af / at / bt PoE technology, this cable 18 allows for both ultra-high-speed data transmission—that is, at a rate exceeding 500 megabits per second, here greater than or equal to 1 gigabit per second—and the transmission of approximately 15 watts of electrical power. Commercially available, PoE, as an alternative to wireless charging through a window, allows the indoor unit 12 to power the outdoor unit 11 even with a thick window 13, preventing excessive window heating and high energy loss. This technology is well-known to those skilled in the art, so we will not describe it in further detail.

[0067] Furthermore, this electrical connection is necessary for the outdoor unit 11. Indeed, only the indoor unit 12 is connected to a power source 27 via its router 24. In this case, this source 27 is an external 12V-58V DC charger. Unit 12 also includes an AC / DC transformer to supply the router 24 with direct current. Therefore, it is Unit 12 that supplies power, via cable 18, to Unit 11 located on the exterior wall. The voltage at the terminals of the router 23 of Unit 11 depends on the type of PoE used: in the case of passive PoE, the voltage at the terminals of the router 23 is determined by a voltage converter to convert the voltage supplied to the router 24 to the voltage suitable for the router 23. In the case of active PoE, the voltage converter is not necessary.

[0068] But how do you position the 18 cable using "PoE"? As mentioned above, the invention takes advantage of the play between the vast majority of windows and the frames to which they are attached, at the level of their axis of rotation. This play is generally filled by an insulating seal. In the embodiment illustrated in the figure 2 This gap is filled by an insulating seal 19 at the axis of rotation X of the window 13 relative to the wall 14. This flexible seal 19 is designed to fill this gap by insulating the window 13. The flat cable 18, 2 millimeters thick, is designed to be inserted between the window 13 and the flexible seal 19 when the window 13 is open. It can therefore connect unit 11 to unit 12, and vice versa, to transmit ultra-high-speed data and electrical current. When the window 13 is closed, the cable 18 compresses the seal 19, which is not a problem since the latter is flexible. The data transmission and electrical connection methods are therefore unobtrusive and remain discreet. They can also be easily removed, as it is sufficient to remove the cable 18.

[0069] We will now describe the components of each unit while simultaneously describing the data transmission along this system 1, starting from station 15, which communicates with the outdoor unit 11. This station 15 belongs to a 4G network, but it could also belong to a 4G+, 5G, or any other type of data network capable of delivering a minimum throughput of 500 megabits per second. The outdoor unit 11 has an antenna device 21 designed to extract at least 1 gigabit per second of data from station 15. Rather than antenna device, we could also refer to it as a wireless transmission interface. To achieve this extraction rate, the antenna device 21 includes a flat antenna, measuring 10 x 10 centimeters. It is a broadband antenna and covers a minimum gain of 6 dBi for all frequencies below 6 GHz used by mobile networks.Within unit 11, this equipment 21 is connected to a radio device 22, which is a modem. The connection between the equipment 21 and the modem 22 is made via a coaxial cable. This modem is capable of controlling the characteristics (operating frequency, polarization, radiation pattern, tilt, etc.) of the antenna 21. This modem 22 is a Category 18 LTE-A modem, operating at 1.2 Gigabits per second. It could also be a Category 20 LTE-A modem (2 Gigabits per second), a 5G-NR modem, or an equivalent modem. By interfacing the antenna equipment 21 with this modem 22, unit 11 is capable of extracting at least 1 gigabit per second of data from the network 15. Furthermore, it is certainly capable of extracting 500 megabits per second. This data is transmitted, via Ethernet link (but it could be a USB link or an internal bus) to a router 23 which must be able to process data received at this high rate.To this end, router 23 features a dual-core processor with a clock speed exceeding 800 MHz, a modem, and a 10 Gigabit Ethernet port. For a data rate of approximately 500 Megabits per second, a 1 Gigabit port would suffice. Furthermore, it has IP routing capabilities, allowing connection to one or more other units, specifically the indoor unit 12. In this way, transmission at a rate exceeding 1 Gigabit per second, and even more so exceeding 500 Megabits or 750 Megabits per second, is ensured from network 15 to router 23, which is capable of handling this data rate.

[0070] Next, this data must be transmitted, still at ultra-high speed, to unit 12 located in the interior room, and therefore placed on the other side of the window 13 wall. To do this, the data is transmitted via the Ethernet cable 18, passing through the gap located between the window 13 and the insulation seal 19, and which carries the data at a rate of more than 1 gigabit per second to unit 12.

[0071] Within the indoor unit 12, a router 24 receives the data transmitted via cable 18. It should be noted that both router 24 in this unit 11 and router 23 in the indoor unit 12 have a PoE port to transmit and extract the data and power from cable 18. The specifications of router 24 are identical to those of router 23 in the outdoor unit 11. They could, of course, be superior in terms of performance. Router 24 transmits the data, via an Ethernet connection (but it could also be a USB connection or an internal bus), at ultra-high speed to a radio device, or modem 25. This modem 25 is of the 802.11ac dual-radio MIMO 3x3, triple-radio MIMO 2x2, 802.11ax, or equivalent type, in order to transmit data at ultra-high speed. This modem 25 transmits this data to an antenna device 26 via a coaxial cable.This antenna system 26 is a dual-band type, enabling Wi-Fi speeds exceeding one gigabit per second. Data is transmitted via Wi-Fi from the antenna equipment 26 to the computer 16 located inside the room. The characteristics of the antenna 26 are not necessarily determined by the modem 25 and can be set during manufacturing. To ensure its discreetness, Laser Direct Structuring (LDS) techniques can be used in its fabrication.

[0072] Thus, data from the mobile network 15 is transmitted at ultra-high speed to the computer 16, that is, at a rate exceeding 500 megabits per second, and especially exceeding 1 gigabit per second when the mobile network from antenna 15 allows it, the elements of system 1 being all specifically chosen to support such a rate. In the opposite direction, that is, in the uplink, the rate can be lower, for example, on the order of 100 megabits per second.

[0073] We will now describe an installation procedure 100 for system 1, with reference to the figure 3 In step 10, an installer places the two units 11 and 12 on either side of the window 13. To optimize signal transmission, it is advantageous to position the outdoor unit 11 on a window 13 oriented so that no obstacle impedes the transmission of waves from the radio station 15 to the unit 11. Regarding the indoor unit 12, it is also advantageous to place it in the most open space possible, or at a height, so as to best cover the interior space and in particular the terminal 16. In step 20, the installer attaches the units 11 and 12 to each other using the magnets 17 so that the units 11 and 12 are fixed together by clamping against the wall of the window 13, the magnets 17 attracting each other through the wall.If one of the variants described above relating to magnets is implemented, a preliminary step of selecting magnets is necessary to adapt the magnetization according to the thickness of the window. It is even possible to test several magnet assemblies to choose the appropriate adhesive strength.

[0074] In step 30, the installer connects cable 18 between the two units. To do this, they connect one end of cable 18 to one of the units, open window 13, and pass the cable between window 13 and the insulating seal 19 of that window, in order to connect the other end of cable 18 to the other unit. Then they close the window, ensuring that cable 18 compresses the flexible insulating seal 19 without obstructing the opening or closing of the window. Finally, in step 40, the installer connects the indoor unit 12 to the power supply 27, so that the entire system 1, and in particular unit 11 via cable 18, can be powered.

[0075] The invention is not limited to the embodiments presented, and other embodiments will be readily apparent to those skilled in the art. The described components enable a downstream throughput of 1 gigabit per second or more, and an upstream throughput of 100 megabits per second or more. The antenna, radio, and router equipment mentioned, which enables this throughput, is commercially available. By definition, they also allow lower throughputs, specifically on the order of 500 megabits per second or 750 megabits per second downstream.

[0076] It is possible to vary the characteristics of the unit components, provided of course that these elements allow data to circulate at ultra-high speed.

[0077] Finally, an embodiment of the invention adapted to a window has been described. However, the described data transmission system 1 can be installed on any type of wall comprising a hinged sash on a fixed frame. Indeed, it comprises a first data transmission unit 11 and a second data transmission unit 12, intended to be positioned respectively on either side of the wall, regardless of the wall's material. It also includes wired data transmission means 18 between the two units 11 and 12, which are designed to extend through the wall, passing between the sash and the fixed frame, to transmit data from one unit to the other at a rate greater than or equal to 500 megabits per second.Finally, system 1 includes wired means 18 for electrical connection between the two units 11 and 12, also designed to extend through the wall, passing between the sash and the frame, to transmit an electrical current from one unit to the other. In particular, it is advantageous to run all these wired means between the frame and the sash at the axis of rotation of the sash relative to the frame.

[0078] These characteristics therefore do not depend on the type of wall, so the system can be installed on walls other than windows.

[0079] Similarly, according to the installation method described, the wall on which the system is installed has a flexible seal 19 between the sash and the frame, and in step 40 the data transmission means 18 and the electrical connection means 18 are extended through the wall between the sash and the seal 19, so that, once extended, the data transmission means 18 and the electrical connection means 18 do not interfere with the opening or closing of the sash. This method is therefore also adaptable to any wall comprising a sash hinged on a frame and a flexible seal located between the sash and the frame, particularly at the axis of rotation of the sash on the frame.

[0080] In another embodiment not shown, the system includes a mounting bracket placed against the inner surface of the wall, in place of the indoor unit. It is designed to attach the outdoor unit to the wall by mutual attraction using the magnet systems described above. Specifically, this bracket has four slots 31 or equivalent; it may be a four-legged support consisting of nothing more than these four slots. In this way, the indoor unit can be placed anywhere within the slot and connected to the outdoor unit by a long flat cable. In other words, in this embodiment, the outdoor unit is arranged in the same way as in the previously described embodiments, but instead of being attached by mutual attraction to the indoor unit on either side of the wall, it is attached by mutual attraction to a four-legged support that serves solely as a mounting bracket.This mode is advantageous in cases where it would be essential to place the indoor unit in a location other than the window, for example at ceiling level or in a central position in a room.

[0081] In a variant of this mode, the quadruped has a Wifi module, making it an indoor data transmission unit.

[0082] In another, unillustrated embodiment, the system includes a platform designed to recreate an artificial wall thickness. Thus, if the wall is too thin for the generated magnetization, the adhesive force of the units may be too great, causing clanging noises or even breaking a window. Furthermore, it can be difficult to handle the unit if it is too strongly attracted to the wall. To reduce this force, the platform is inserted between one of the units and the wall, artificially increasing the wall thickness and the distance between the two units. This is an alternative to the variant with the figure 9 described above to decrease the adhesion force.

[0083] In one variation of this design, the platform acts entirely as a wall, eliminating the need for a window or other wall. The indoor and outdoor units are then mounted on either side of the platform, forming a single unit that can be placed on any horizontal surface. This arrangement is advantageous when a conventional wall or window is unavailable. For example, in a temporary setup in an outdoor tent where an internet connection is required, the units normally placed on a window in the home are relocated, mounted on either side of the platform, and the entire assembly is placed inside the tent. The complete system is then configured as a single unit.
